After a few days of using my personal UI I decided to share it with others to ease up their lives.
It is a clean and easy for the eye with four quick bars, two on each side, the minimap in the middle and a large personal, group, target and target of target portrait, oh and the companion too!

Space combat has also been slightly altered.

I hope you all enjoy and feel free to alter it and upload newer or better versions here.
